Title: Modular step exercise unit
Inventor: WILKINSON WILLIAM T
IPC: B23D35/00
Filed: 1994-07-06
Abstract: MODULAR STEP EXERCISE UNIT               Abstract of the Disclosure A modular step exercise unit includes a plurality of individual steps.  Each step is in the form of a base having a horizontal platform which comprises the upper surface of the base with depending sides forming an apron which terminates in a plane parallel to the platform so that the apron can be placed directly on a support surface, such as a floor.  The steps may be made of differing size so that during storage or even in certain use conditions, steps which are not being used can be stored within the periphery of the apron of the largest step.  A multi-level step can be formed by mounting a smaller step on a larger step.  The individual steps could be used abutting each other or spaced from each other to provide a multi-level arrangement which includes individual steps and the floor.  If desired the steps could be of the same size as each other which would eliminate the advantage of storing the steps within each other during non-use, but would have the advantage of providing a more symmetrical exercise unit by equal sized steps.

Patent CA-2141618-A1 (CA)
Title: Protective wear-blade
Inventor: THOMAS JULIAN P
IPC: E01H5/06
Filed: 1995-02-01
Abstract: This invention relates to the problems associated with snow removal from the top-level of multi-level, open-air parkades located across Canada. The two serious problems peculiar to these types of parkades are: one, all of them are unusually vulnerable to corrosion from street-salt, and, two, all pose or cause serious parking problems at the top level during the winter months. In order to prevent, or at least to mitigate, the problem of corrosion, a chemical called Isoflex 750 is applied to the entire surface of the top-floor of this type of parkade. This chemical forms a waterproof membrane. This membrane causes serious problems during snow removal operations, because snow removal must be accomplished without damaging the membrane, so as not to destroy its waterproofing quality. The most preferred, and the most common method of snow removal involves the use of front-end loaders. In order not to damage the membrane, the loader blade is kept from two to four inches above the surface of the membrane throughout the entire clearing operation...thereby leaving a snow-pack over the entire parking surface for the duration of the winter. It is this layer of ice and snow that causes a variety of serious parking problems throughout the winter months...especially when cars become "trapped" at the very top of the parkade during a snowfall. Also, when this layer of ice and snow eventually melts, much of this water finds its way down to the lower levels of the parkade and adds to the over-all corrosion problems peculiar to this type of structure. This invention called "The Protective Wear-Blade" is an enabling-device which makes it possible for a front-end loader to remove all of the snow from the top-level of an open-air parkade.
Patent CA-2142432-A1 (CA)
Title: Dynamoelectric machine with brush having slanted core
Inventor: NOWICKI HENRY B
IPC: H01R39/18
Filed: 1995-02-13
Abstract: Core-type brushes used in dynamoelectric machines, such as electric motors, have cores which are arranged in substantially parallel planes extending at an angle with respect to the direction at which the brushes move toward the commutator as the brushes wear. As the brushes wear, the position of the cores relative to the outer surface of the commutator changes, preventing constant positioning of the cores relative to the commutator surface and reducing or preventing non-uniform commutator wear which occurs when the cores maintain a fixed position with respect to the commutator surface as the brushes wear. This arrangement of the cores eliminates the need to resurface the commutator at brush change, reduces the time required to properly seat the brushes to the commutator and increases commutator and brush life.

Title: Apparatus and method for dispensing and distributing loose particulate materials
Inventor: REXIUS ARLEN L
IPC: B60P1/38
Filed: 1995-02-28
Abstract: A truck including a container used to transport and dispense loose particulate materials. A moving floor is located on the floor of the container to move looseparticulate materials within the container into a feeder and dispensing system. The container includes two opposing augers mounted on the inner surface of a rear door of the container. The augers feed loose particulate material within the container to a mixer. The mixer helps to break up the loose particulate material to keep it from bridging as it drops into a feeder. The feeder regulates the flow of loose particulate material into a mixing chamber. A high volume air blower is connected to the mixing chamber. The blower forces a high volume of air through the mixing chamber and out of the mixing chamber into an attached hose. As loose particulate material drops into the mixing chamber, it mixes with the air flow and is blown out of the attached hose. Prior to entering the mixing chamber, the air stream from the blower may be mixed with water to produce a mist. The water mixed with the air stream mixes with theloose particulate material, helping to prevent the production of airborne particles.

Title: Method and apparatus for anchoring a wellbore tool to a casing in a wellbore including a primary and a secondary anchor release mechanism
Inventor: HUBER KLAUS B
IPC: E21B23/04
Filed: 1995-03-28
Abstract: A wellbore tool comprises an anchor apparatus connected to a perforating gun including an anchor slip for expanding to grip a casing in the wellbore when the wellbore tool is disposed in a wellbore, a primary anchor release mechanism for upsetting the anchor apparatus and a secondary anchor release mechanism for upsetting the anchor apparatus when the primary anchor release mechanism was not activated. If the primary and secondary anchor release mechanisms have not been activated, the anchor apparatus can set the anchor slip.      The anchor apparatus includes upper and lower slip housings, and an anchor slip disposed between the upper and lower slip housings.      Provided both the primary and secondary anchor release mechanisms have not been activated, the anchor slip will expand radially outwardly when the upper slip housing physically approaches the lower slip housing. The primary anchor release mechanism automatically upsets the anchor slip of the anchor apparatus when a detonation wave propagates through a detonating cord, through an interior space of a frangible member thereby shattering the frangible member and detonating the perforating gun. If it is necessary to upset the anchor slip of the anchor apparatus without shattering the frangible member and detonating the perforating gun, a secondary anchor release mechanism includes a release sleeve adapted to attach to a separate shifting tool and an upset. When the shifting tool is attached to the release sleeve, an upward or downward movement of the shifting tool will cause the upset to move away from a first collet finger. When the upset moves away from the first collet finger, the anchor slip can be upset without shattering the frangible member or detonating the perforating gun.
